chihaya04 Sure! There's some basic information on this blog, though a lot of it is outdated: https://webnovelblogcom.wordpress.com/webnovel-faq/
Mostly the bits about being able to apply are incorrect as confirmed by someone on the Discord server. You have to wait for the Content Editors to contact you to get an exclusive contract. (Usually, this is after having a decent number of chapters and words.) However, for the non-exclusive contract, you do have to email EMP Publishing to get a copy of the agreement. (I personally did this after being contacted about the exclusive contract, but I have no idea if you can email before then.)
You can add me on Discord (my username is on my Webnovel profile) or just ask something specifically on the forums if you want any other information! There's also a lot of info on the Webnovel Discord server. 😄
